Send feedback →Feature overview
AI auto-annotation, the pending-review workflow, VOC & YOLO export and the annotation checker — what FlyLabelImg does and how it compares.
See all features →How to write a bug report we can actually fix
Most reports bounce back and forth because one of these is missing. Including all six usually gets a fix or a workaround in the first reply.
- FlyLabelImg version — Help → About. Also say whether it is the installer or portable build.
- Windows version — for example Windows 11 23H2 or Windows 10 22H2.
- What you did — the exact steps, in order.
- What you expected to happen.
- What actually happened — include the wording of any error message.
- How to reproduce it — does it happen every time, or only with a particular file? If specific files are involved, describe their size, count and annotation format (VOC or YOLO). Please do not attach confidential files; a small sample is enough.
You can send this in the feedback form on the home page, or straight to support@flysoft.vip.
Common questions
Is FlyLabelImg free?
Yes — there is a 30-day free trial with every feature enabled, and no sign-up. Licences are one-time purchases ($39 for 1 year, $99 for 5 years) that keep the software registered and include updates for the licence term.
I bought a licence but never received the email.
Check your spam folder first, then use the Lost your license? form in the download section of the homepage to have it re-sent automatically. If it still does not arrive, email support@flysoft.vip with your purchase email address.
I replaced my PC — can I move my licence?
Yes, free of charge. Email us from the address used at checkout with the new machine's device code (Help → License Management → copy the device code) and we will re-issue it.
Does FlyLabelImg upload my images anywhere?
No. AI inference runs locally on your machine — your images never leave it. There is no telemetry and no background network activity; the only outbound request is the licence check, and only if you register. See the privacy policy for the full detail.
Are macOS and Linux versions available?
Not yet — FlyLabelImg is currently Windows 10/11 (64-bit) only.
Before you contact us
A few things solve themselves, and it is worth trying them first:
- Update to the latest version — your issue may already be fixed.
- If AI annotation says the service is offline, start the bundled FlyLabelAI tray program — it launches the local llama-server automatically — and wait for the status dot to turn green.
- For AI timeouts, lower the concurrency in the model settings (a single consumer GPU processes one image at a time) or raise the timeout for large images.
- For missing annotations after reopening a folder, check the format switch in the status bar (VOC reads XML, YOLO reads txt) and that the sidecar files sit next to the images.
- For duplicate boxes after AI runs, that is expected only if the class differs — same-class near-duplicates (IoU > 0.7) are removed automatically.
Still stuck? support@flysoft.vip — we would rather answer an easy question than have you stuck on it.
